Isaiah 59:1–2 (NKJV)
1 John 1:8-9 (NKJV)

“Behold, the LORD’s hand is not shortened,
That it cannot save;
Nor His ear heavy,
That it cannot hear.
But your iniquities have separated you from your God;
And your sins have hidden His face from you,
So that He will not hear.”

“If we say that we have no sin, we deceive ourselves, and the truth is not in us.
If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness."

2 Timothy 2:4-5 (NKJV)

"No one engaged in warfare entangles himself with the affairs of this life, that he may please him who enlisted him as a soldier. And also if anyone competes in athletics, he is not crowned unless he competes according to the rules”

Ezekiel 36:25-27 (NKJV)
Ephesians 5:18, 26-27 (NKJV)

"Then I will sprinkle clean water on you, and you shall be clean; I will cleanse you from all your filthiness and from all your idols. I will give you a new heart and put a new spirit within you; I will take the heart of stone out of your flesh and give you a heart of flesh. I will put My Spirit within you and cause you to walk in My statutes, and you will keep My judgments and do them.”

“And do not be drunk with wine, in which is dissipation; but be filled with the Spirit,”

“that He might sanctify and cleanse her with the washing of water by the word, that He might present her to Himself a glorious church, not having spot or wrinkle or any such thing, but that she should be holy and without blemish.”
